Answer this question truthfully
### Question: What to expect if I have Acute renal failure  (Outlook/Prognosis)?
### Response: Acute kidney failure is potentially life-threatening and may require intensive treatment. However, the kidneys usually start working again within several weeks to months after the underlying cause has been treated.
In some cases, chronic renal failure or end-stage renal disease may develop. Death is most common when kidney failure is caused by surgery, trauma, or severe infection in someone with heart disease, lung disease, or recent stroke. Old age, infection, loss of blood from the intestinal tract, and progression of kidney failure also increase the risk of death.
